• Greenhouse effect


  • Radiation from the earth's atmosphere warms its surface to a temperature higher than it would be without it
  • Greenhouse gases are to blame
• Effects of global warming

  • Temperature rises on average
  • Seasonal changes
  • Severity of harsh weather events
  • Water and food shortages
  • Increased health risks
  • Coastal inundation
  • Increased frequency and intensity of cyclones and hurricanes
• As the earth's temperature rises, a huge amount of ice melts, causing a large volume of water to flow into the ocean, raising the sea level
• Since ice caps and glaciers have begun to melt, species that reside in such habitats have begun to relocate, potentially leading to extinction due to habitat loss
• Because of the vast volume of water evaporated into the air as the sea level rises, high levels of precipitation will occur, and the earth will suffer intense rains or storms
• Carbonic acid is created when carbon dioxide dissolves in sea water, acidifying the ocean as indicated by a pH shift
• Animals produce a lot of methane. Some fertilizers also produce nitrous oxide, a greenhouse gas that contributes to the rise in global temperatures
• Climate change


  Changes in weather patterns and growing seasons all around the world
• Climate change is a result of global warming, and it poses a severe threat to human life on the planet in the form of widespread flooding and catastrophic weather
• Typhoon Haiyan, also known as Super Typhoon Yolanda in the Philippines, was one of the most intense tropical storms ever recorded and was caused in part by climate change
• Yolanda was said to have been caused by global warming and climate change
• Indicators of climate change

  • Rising sea levels
  • Habitat destruction
  • Ocean acidification
  • Extreme weather
• Climate change will have an impact on every area of society, the environment, and the economy. Human behavior, livelihoods, infrastructure, laws and regulations, and institutions are all likely to be impacted
• Adaptation to climate change

  1. Practice conservation of natural resources

  2. Reduce pollution and waste
• Reducing pollution and waste

  • Using a reusable bottle or cup for on-the-go refreshments
• These occurrences in various parts of the globe have an impact on all people on the planet
• All attempts to understanding and predicting the possible implications of climate change are dominated by uncertainty
• Climate change will have an impact on every area of society, the environment, and the economy
• Human behavior, livelihoods, infrastructure, laws and regulations, and institutions are all likely to be impacted by climate change
• Adaptation to Climate Change

  1. Practice conservation of natural resources

  2. Reduce pollution and waste

  3. Reuse water

  4. Recycle products

  5. Conserve energy
• Conservation


  Taking care of natural resources (air, water, soil, minerals, plants, animals) so that all living beings can benefit from them now and in the future
• Reducing pollution and waste

  • Use reusable bottle/cup
  • Use reusable supermarket bags
  • Make prudent purchases and recycle
  • Compost fruit/vegetable waste
• Reusing water


  Collecting water used in the shower to flush toilets or water gardens
• Newspapers, magazines, mixed paper, cardboard, tin cans, aluminum cans, glass jars, and plastic containers are examples of products that can contain recycled material
• Energy conservation


  Reducing energy consumption by using energy more efficiently or lowering the amount of service provided
• Adaptation is a long-term process of making lasting changes in response to climate change, with strong policy connections to economic development, poverty reduction, and disaster management measures
• Successful adaptation programs will include long-term thinking and consideration of climate change implications at the international, national, regional, municipal, and community levels
• Climate change vulnerabilities, relevant technologies, capability, and local coping strategies, as well as government policies and actions, must all be considered in adaptation planning
• The IPCC defines adaptation as "adjustment of natural or human systems to existing or anticipated climatic stimuli or their effects that mitigates harm or leverages favourable opportunities"
• Adaptation has a high price cost. Developing nations will need between 28 and 67 billion dollars by 2030 to adapt to climate change
• Adaptation isn't a one-off problem. It will have to be factored into all future growth plans
• To deal with uncertainty, adaptation methods must be robust against a variety of potential climatic outcomes
• Citizen engagement and awareness are required to maintain and prioritize climate change actions
• Transnational migration occurs when people move from one country to another while maintaining their social ties
• Factors of Transnational Migration

  • Overpopulation
  • Poverty
  • Underemployment
  • Unemployment
  • Low wage level
• Overpopulation


  People flee to neighboring nations as a result of overpopulation. These people relocate to other countries because they believe their current home no longer has adequate space for them
• Economic factors


  People migrate to other nations in pursuit of better economic opportunities for their families. They send the money to their relatives in their home country
• Overseas Filipino Workers (OFWs) are a well-known example of transnational migration
• According to the 2011 Philippine Overseas Employment Agency (POEA) report, the Philippines has 10, 455, 788 million OFWs spread throughout 236 countries and territories, making it one of the top three labor-sending countries in the world, after India and China
• Remittances made for 12.65 percent of the Philippines' gross domestic product in 2012
